The male ending is = Khrap
The same phrase is also used to say goodbye.
Khrap (Yes) / Mai Khrap (No) –Male
Don’t forget to add the polite ending to each of these phrases; Kha for females and Khrap for males. Although you may make mistakes and may not understand the fast paced Thai reply to the questions. It is polite to try to ask in Thai, it is nice to feel slightly less ignorant and vendors will appreciate this and almost always give you a lower price or more bargaining room.
